Distance Overestimation Error Correction Method (DOEC) of Time of Flight Camera Based on Pinhole Model

摘要: Depth cameras with Time of Flight (ToF) technology are widely used in machine vision and various measurement tasks. However, due to hardware conditions imaging characteristics, multiple errors limit the further application ToF camera. This paper classified into caused by non-imaging principle error principle. In order simplify experimental procedure improve efficiency correction, a simple feasible method is correct principle, an evaluation function proposed determine optimal reference distance, so as select appropriate integration time global offsets. To tackle radial distance error, Distance Overestimation Error Correction (DOEC) based on pinhole accuracy depth data. Finally, correction methods this verified experiments, segmentation different ranges successfully achieved using modified data, prove effectiveness methods.
